1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Propionate, a fermented product in the lumen of the large intestine, is a short-chain fatty acid (SCFA) known to have a variety of localized physiological and pathophysiological functions (e.g., luminal fluid secretion and anti-inflammatory response). In the present study, we investigated propionate-induced transepithelial ion transport and the expression of SCFA receptor, free fatty acid receptor 2 (FFA2, otherwise known as GPR43) in the guinea pig distal colon utilizing the Ussing chamber technique and immunohistochemistry. The addition of propionate to the luminal bathing solution concentration-dependently induced transient K(+) and Cl(-) and/or bicarbonate secretion within approximately 30 s and long-lasting Cl(-) secretion for approximately 60 min was first identified in the present study. The transient anion secretion was tetrodotoxin (TTX)-sensitive and mediated through the cholinergic (both nicotinic and muscarinic) neural pathway, but the transient K(+) and long-lasting Cl(-) secretion were due to TTX-insensitive mechanism. Immunohistochemistry studies showed that some chromogranin A-immunoreactive enteroendocrine cells were also immunoreactive for FFA2 but not colocalized with 5-hydroxytryptamine. In conclusion, the propionate-induced secretion consisted of the neural and non-neural three-phase secretory manner possibly mediated by the stimulation of FFA2 expressed by enteroendocrine cells.
